My only exposure is that flash mob commercial running on TV right now. I can't in my right or wrong mind picture a group of 20 or more people who would text each other and then take the time to devise and then practice some goofy routine, then take time off of work probably to meet at some place and then at a certain time, jump up- do the routine then "disappear" into the crowd. Unless they're all artsy-fartsy liberals. Then I understand. They're expressing themselves. Where's the puking Smilie when you need him?
